Anker - Nano Power Bank, Ultra-Slim 5,000mAh Magnetic Battery Pack, 15W Max Ultra-Fast MagSafe-Compatible Portable Charger - Black

Bought this model because it was supposed to charge and stay cooler than other models. This unit will probably get you around 60-70% charge on most phones. It’s 5000mh but is lite enough so that the phone isn’t too heavy. It does get warm, but not hot. I was at an outdoor event with it in my pocket, but didn’t add much weight. The magsafe feature works good, I would like for it to be a little stronger. I have an iPhone 15pro with an Apple magsafe case. It wasn’t so loose that it was an issue. I have several (probably too many) Anker products. This one is made well and would recommend for adding some battery life without the weight.

Slim and very good product. This is all you need really!If you always have this slim powerbank charged and make it a part of you everyday carry you don't have to worry about your iphone being low on battery. It is best for every day but also for travel. Fits in any pocket as it is very slim. Charges phone without stress of carrying a bulk powerbank! It looks cool on the phone too and magnet is strong. I love this little product. Its all I need for extra power juice. I never go anywhere without it. I absolutely recomend it!!

I usually go thru so many of these powerbanks - most of them are not very rememberable or given as swag, etc. This one feels premium, sleek and is about the same width as my phone without a case. It charges my phone about 1.5x times fully and the magsafe works fine. I do not have any complaints. It seems to charge quickly and offers pass thru charging.

My main phone is a Pixel 10 Pro so it has Qi2 magnetic wireless charging (Magsafe for Android, basically), which turned out to be handier than I expected. This battery pack is not much bulkier than the magnetic card holder I use if I'm not carrying my wallet, and charges transparently without having to deal with cables or even taking my phone out of my pocket. The one thing I would say is that you need a magnetic phone case for this to work - the Qi2 magnets are not strong enough to really work through even a thin phone case. The upshot of this is if you get a magnetic phone case for a phone WITHOUT magnets that you can replicate Magsafe on any phone with wireless charging.

I like that it is small and doesn't feel heavy on the phone. It charges my phone, and it did not get hot.
